need serious help

I just got an ipod touch from a friend. when i plugged it into my computer it disabled the ipod touch. I cant use the ipod at all. Is there any way that i can enable the ipod and get it working. I've tried restoring it but it didnt work. My iTunes does not even recognize the ipod touch when i plug it up to my computer. Please help

This is because it should only be used with one computer. I recommend restoring it on his/her computer and then sync it with your computer if it is in recovery mode. Then, you can have all of the stuff in your iTunes and not your friends'.
